Hi I tried other versions of mandrake and mandriva before and never had this problem. I installed Mandriva 2007 and initially internet connection was fine then started to be very sluggish or not working at. Computer is connected to the router via ethernet cable and served by DHCP there is another computer connected via ethernet and wireless broadcasting. But I am interested in getting to work only one of them the one on ethernet. If I connect ethernet directly to cable modem everything is fast and fine but when it is pluged into router then the problems begin. No problem working undeer windows DHCP is set to distribute 3 numbers.

Really appreciate your help guys. I did a search but answers I found were about wireless and ndis wrapper

Sounds like it could be a problem with ipv6. Disable ipv6 by adding this to /etc/modprobe.conf

 

alias net-pf-10 off

 

that might help, you can also do it in the browser, with Firefox, type "about:config" without the quotes, and then filter by ipv6 and set it to true to disable ipv6 within the browser.

There's a few ways to disable ipv6, which I wrote here:

 

https://mandrivausers.org/index.php?act=ST&...=22&t=35816

 

problem is, I've read in some places on some that may or may not work. The easiest way is run the ifconfig command after the reboot, and if you're getting inet6 against it, then ipv6 hasn't been disabled.

 

The alias command I listed always seems to work, but I included the others for completeness as is nice to know different ways of doing things :P

 

Hope it sorts it.

In all honesty, there's no real reason to use ipv6 just yet. It's not taken off as such, although the support is there for it. You'd be best disabling for now, as and when it becomes more common-place, then it can be re-enabled where necessary.

Hi looks like I turned off ipv6 :

[root@localhost darek]# ifconfig -a
eth0	  Link encap:Ethernet  HWaddr xxxxxxxx
	  inet addr:192.xxxxxxx  Bcast:xxxxxxxxx
	  Mask:xxxxxxxx.0
	  UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
	  RX packets:489 errors:0 dropped:0 overruns:0 frame:0
	  TX packets:592 errors:0 dropped:0 overruns:0 carrier:0
	  collisions:0 txqueuelen:100
	  RX bytes:413297 (403.6 KiB)  TX bytes:76202 (74.4 KiB)
	  Base address:0xac00 Memory:fe000000-fe020000

but the proble is still there

 

[root@localhost darek]# route -n
Kernel IP routing table
Destination	 Gateway		 Genmask		 Flags Metric Ref	Use
Iface
192.xxxxxx	 0.0.0.0		 255.255.255.0   U	 10	 0		0
eth0
169.254.0.0	 0.0.0.0		 255.255.0.0	 U	 10	 0		0
eth0
0.0.0.0		 xxxxxxx	 0.0.0.0		 UG	10	 0		0
eth0

 

I have no idea what else it might be

Can you ping the router OK? What's the contents of your /etc/resolv.conf?

 

Hi, pinging seems to be o'key

[darek@localhost ~]$ ping xxxxxxxx

PING xxxxxxxx) 56(84) bytes of data.

64 bytes from xxxxxxxx: icmp_seq=1 ttl=64 time=0.614 ms

64 bytes from xxxxxxxx: icmp_seq=2 ttl=64 time=0.612 ms

rtt min/avg/max/mdev = 0.535/0.578/0.614/0.042 ms

resolv.conf

 

search xxxxxxxx.

 

nameserver xxxxxxxx

nameserver v

problem seems to be very wierd I can conected to certain websites but not to the others then few minutes later I cannot access websites I could reach before, then after few minutes firefox is just spinning around.

Could it be some DNS problem?

Thanx

I'd be tempted to edit the resolv.conf and remove that line:

 

search hsd1.nk.comcast.net

 

these search lines can slow down DNS, and you don't really need them anyway. I suggest remove that, make sure that the nameserver entries are correct, then try for example:

 

host linux.org

 

if it replies with ip addresses, then DNS is working fine, but remove that search line first. Hopefully you're using a static ip address, as if DHCP you might get the search line back again next time you reboot.

I had DHCP but switched to static IP. I removed search line and put two of my ISPs DNS servers which appeared to be most reliable. Internet connection is now working much better but stilll there are moments when I have to wait a while. Once again thanx a lot and I will keep on educating myself how to improve the connection
